Answer 1

PART C

pent-2-yne

• Alkenes and alkynes are named by identifying the longest chain that contains the double or triple bond.
• The chain is numbered to minimize the numbers assigned to the double or triple bond.
• The suffix of the compound is “-ene” for an alkene or “-yne” for an alkyne.

PART D

3-Methylcyclopentene

Structure

Alkenes are compounds that consist of carbons and hydrogens bonded together with a carbon-carbon double bond. Cycloalkenes are alkenes that consist of three or more carbon atoms linked together with at least one carbon-carbon double bond to form a structural ring

Naming Rules

Cycloalkenes are named the same way that open chain chained alkenes are, with the exception that the numbering is started at one of the carbons of the double bond in order to keep the index numbers as small as possible.
